I tried to install windows (xp, vista or seven) 32 and 64 bits, in my mac mini Late 2009, and when i create the partition with bootcamp, restart and the monitor give black screen, the dvd is reading, but the monitor don´t display nothing.

Maybe someone else could get in on this post that has the same machine. I just do not think it has anything to do with the monitor setup if that was working before in mac._________________-2012 MacMini, i5/2.5 Ghz./16 GB RAM.

I would also try it with the Mini-DVI port. That Mini DisplayPort can be a bag of hurt. Then again, what happens when you hold down you option key at startup? Do you get a picture and option to get back into Snow Leopard? Like what have you been doing after getting the black screen?_________________1.42GHz Mac mini
